"As part of a drug investigation, the Pasco County sheriff's Department once installed a 17-year-old runaway and her 18-year-old friend in a mobile home, where the young women sometimes traded sex for drugs. The mother of the 17-year-old girl had already reported her daughter as a runaway and had asked the Sheriff's Department for help in finding the girl, a juvenile. Meanwhile she was being used in the investigation without her parents' knowledge. . ."
